As there are many techniques for assessing hydration measurements, they differ in their applicability due to their type of methodological significance. Each method has different limitations depending on their methodological synthesis techniques, such as the circumstances necessary for measurement, sensitivity and precision, system installation, ease and cost of the system. Sports Science Exchange summarized hydration assessment methods for assessing total body water in the Hydration Assessment article. athletes.[10] In which the following main types of methods describe those used to access in vivo measurement of total body water.1. Dilution techniques based on laboratory analysis: Urine markers, such as an osmometer, refractometer which assess osmolarity, density, color.2. Plasma markers whose measurement was linked to changes in osmolality, sodium, hematocrit and hemoglobin3. Changes in body mass4. Use of other related variables such as body temperature, heart rate, sweat analysis, oxygen, blood flow, skin hydration monitoring5. Physical signs, symptoms of clinical dehydration such as skin turgor method.6. Total body water measured by the estimated bioelectrical impedance analysis method. Each method has different methodological limitations depending on their reliability, simplicity and precision. There are precise techniques for measuring water content, namely the osmometer and the reflectometer. But such systems cannot be used as portable devices due to the need for urine or blood samples, and involve a measurement technique that works on the principles of freezing point depression and pressure vaporization (heating and cooling). In clinical evaluation, urinalysis is a frequently used method to detect hydra...... middle of paper ...... rough body as a whole, i.e. extracellular fluids as well as intracellular fluid. The concept behind the multiple frequency BIA method is to take measurements over a range of lower to higher frequencies. From this it is possible to develop a prediction equation from low frequencies to high frequencies. Looking at the immense importance, success and popularity of the bioelectrical impedance analysis method, in our research work we have used this standard method. The accumulation system has evolved taking into account the features and advantages of the complex multi-frequency bioimpedance analysis method. This developed configuration falls under small size and low power integrated devices that can easily access the patient and capture the data in real time. Thanks to these, the device has an integrated intelligence system and control decision-making that helps patients benefiting from integrated treatment..
